To all whom/it mag concern.

Be itknown that ll, GEORGE C. BERLIN, a citizen of the United States, residing at comprises a' nain frame A consisting of [longitudinal sills 5--5 and transverse con- Caldwell, in the county of Canyon, State of Idaho, have invented certain new and useful Improvementsin Driving-Gears; and

I do'hereby declare the following -to be a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which .it appertainsto make and use the same.

"This invention relates to an improvement in driving gears for vehicles generally, a1;- though the invention is more particularly designed to be-used in connection with farm; I

' i front transversefmember 9 of each suplple-.

wagons.

The rincipal object of the invention is to provide a gear for the purpose described which when attached to 'a farm, wagon. will constitute 'what is known as alow farm wagon.

Another object of the invention is to pro-' vide a gear which includes an endless rotating tire which is arranged in such a manher that the wagon can beeasily moved over ditches or obstacles without any. unnecessary jar to the wagon body.

A further ob'ect of the'invention is-to provide a wheel supporting frame, which is pivotally connected at its front end and" resiliently retained at its rear end, whereby thejars incidentto the passage over rough ground will be" greatly reduced."

A still further object of the invention" is to provide a driving gear for the purpose described, which can be easily applied to or detached from any wagon now in. use.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended; it being understood that various changes in the form, PI'OPOItlOIl, size and minor details of construction, within the scope of thezclaim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the inven- In the drawings: Figure 1 is a side elevation of a wagon body illustrating m invention, Fig. 2 is a top plan view 0 the running gear, and Fig. 3 is a transverse sectional view taken on the line 3-?3 of.

spending parts in all the, figures of the drawings. i

Referring to the drawings, the invention necting end sills 6-6. Suitably supported -upon this frame is a wagon body 7. -Disposed below and secured to the mainframe are spaced front and rear supplemental ,.f1'ames Band C. Each of-theseframes:

consists of' longitudinal frame members .88 and transverse members 9--9. Disposed between the supplemental frame B and the nain frame A is a fifth-wheel, 10 of' any suitable construction. Depending'from the mental frame are spaced :pairs' of brac ets 1 1 andl2 respectively. Hingedly connected to these; brackets is a lu'rality of driving mechanisms, each mec anism being, indicated as a'whole by the reference letter B.

deemed to be suificient.

Inasmuch as the construction of each mech- I Each driving mechanism includes a 'fra'me consisting of an end member"l3, a longitudinal member 14, anda, member-.15 'which connects the ends of the, first mentioned members. This frame is'disposed below and at one side of one I of the" supplemental frames, and the transverse member 13 thereof -is pivotally connected'by any suitable mentioned. I'nterposed between the rear end of the longitudinal member 14: and the lemental frameisa coilspring 16. Be-

means to the contiguous brackets before pen ing from. either. end of the longitudinal member-14 are diverging le 5 17' and 18 respect-ively. The lower en s of these legs are connected to a tractor wheel carrying frame, which includes transverse 'members.

19 and longitudinal members .20. Bearings 21 are centrally mounted onjeach member 20, and journaled in said'bearings is an.

axle 22 upon which is mounted a tractor wheel 23. 'This tractor wheel is provided.

with opposed flanges 2424 forming a consequent recess 25. Integral with said. wheel and'pro'ecting upwardly into said recess is a plura ity of sprocket teeth 26. Also mounted on the members 20 at the forward ends thereof are bearings 27 in which isjournaled a. shaft 28, upon which is mounted a wheel 29 similar in construction to the wheel 23 above. referred to, but hav ng a smaller dieter. 4

tudinal members 20 is a tensioning device which is indicated as' a whole by the reference letter E. An axle-35 is journaled in the tensioning device, and mounted upon the axle is a wheel 36, which is similar in construction and preferably of the same size as the wheel 29. Engaged with the sprocket teeth 26 thereof is a sprocket chain 39, this chain beingcadapted to engage the ground below the center wheel 23. It will'furthermore be observed that by means of this driving gear any jar, incident to the passin over stones and the like, will be prevented from passing to the bodyby means of the coil spring 16, which permitsof said driv ing frames having a resilient connection.

A draft-pole (not shown) may be suit ably connected to the supplemental frame B by any well known means, and to this pole may be attached draft animals for drawing the wagon along the ground.

What is claimed is; y

A vehicle comprising in combination, a

main frame, front and rear supplemental frames secured thereto, pairs of driving vertical movements,and compression springs disposed intermediate the rear ends of each supplemental frame and the driving elements, each element consisting of an end member, a longitudinal member, a diagonal member connecting. thefirst mentioned members, diverging legs depending from either elements respectively connected at its for- .ward end to each supplemental frame for end. of the longitudinal member, a'frame' connected to the lower ends of said legs includi'ng spaced longitudinal members a plurality of tractor wheels disposed between and vjournaled inthe last mentioned longitudinalmembers, and an endless belt op-
